For a typical configuration of an Automatic triaxial test system see Additional information. The asttm consists of a hydraulic piston, driven by a ball-screw and gearbox, mounted on a ball-slide, and is managed under closed-loop control.

Strain gauges qstm Uniaxial and Triaxial tests They provide a very accurate electrical signal, strictly proportional to the strain of the Hoek cells can be fitted with optional end caps suitable for permeability test. Home Products Rock mechanics Automatic system for uniaxial and triaxial tests on rock cores including stress path and permeability determination. The water pore pressure is read by a dedicated transducer.
